Let's go then!

You feel pent-up energy in your system as you leave for the day. The gym seems like a good idea after Olive's suggestion, so that's where you end up. At your locker you once again notice how tight your clothing feels, your baggy t-shirt is no longer baggy and your shorts are so tight you consider changing your mind.

But the desire to work wins out and you head up to the machines to pump the iron. The weights you're used to suddenly don't feel so heavy and the amount lifted starts to go up and up. You admire your muscles as you sweat, they look pronounced and vascular. Plus you notice how toned they look, you swear your body fat looks lower. As you're mid-bench press you suddenly hear a "hey!" directed at you.

Pushing the bar back onto the rests you see Sophia. A girl you'd seen now and then but never got the chance to know her properly. Young and beautiful, with a tight waist highlighted wide hips and breasts that were a little too big to be on her small frame. Her six-pack and very toned muscles drove you crazy but she never seemed too interested in chatting.

"Ted! I've not seen you in a while! Looking good my dude! Can you spot me please?" Her dazzling smile and enthusiasm might have knocked you to silence for a minute but you find yourself replying with a smile of your own "Of course, anything for you"

where did that come from? You think to yourself as you follow her over to a squat rack. Confidence was not normally your strong suit.

As you take position behind her, you try your best to avoid looking at the extremely tight leggings that show off an ass that has had a lot of effort put into it. You try to keep some distance, but as she takes her position she looks over her shoulder with another disarming smile "Come closer than that! This is a new weight and I might need your big muscles!"

The stirring in your shorts distracts you as you edge closer. Sophia steps back and lowers herself down one rep after another. Her pinched waist and large toned ass are tantalisingly close as you cover the bar. Until you see her legs shake and you have to step in and help push it back onto the rack.

It's too late to notice that you've gotten completely hard watching her and it's too late to notice that by stepping forwards the log of meat pressing out from your crotch pushes straight against her ass cheek. For an awkward moment, you stand there, close behind her. Her breathing ragged from effort as she slowly looks over her shoulder. "It feels like you enjoyed that," she says with a husky tone "Maybe I can do one more and we can go to the sauna after..."

Unable to say anything, your cock flexes on its own against her causing another grin "I'll take that as a yes" she says.

As you step back you dare to look at the gap between you. Your cock is rock hard and the grey material of your shorts is stretched thin, faint tear marks showing. It's obscene, but as long as you're close to Sophia other people can't see it. You hope.

She backs into you with the weight on her shoulders again and this time purposefully grinds her ass against your crotch before starting to squat. You feel a pulse of excitement. The pressure against you forces you to suppress a groan as the sensation of hot wetness spreads out from your tip.

Before you can think the set is over again and as Sophia slowly pulls away from you, you can see the precum stain on your shorts.

Looking down, she stares and her mouth drops open. "Fuck.. so ummm want me to walk in Infront of you?"

You nod stupidly and proceed to hurriedly walk behind her, doing your best to keep the raging erection hidden from view. You don't fully succeed as you catch a few glances from other gym goers, but no one says a word as you separate at the changing rooms. "Sauna. 5 minutes okay?" Sophia says. You just respond with a nod and watch her skip off with a distinct stain on her ass.
